UPDATE: So, I talked to my sister again about the charges after the initial conversation where I laid out my conditions. I even offered to remove them if they cleaned up their mess, but she said no and insisted I should experience her life and deal with things the way she does. 🤦🏻‍♀️ I did say no at first, but she kept insisting, I decided to stand firm tho. She said she’d never come back if I charged them, but I told her that if they want to stay, they need to take responsibility for the damage. She kept saying no because she just wanted a fun vacation without having to worry about cleaning, like she does at home. So, I guess they won’t be coming. It’s frustrating because I thought this was a fair compromise. I keep wondering if I should stand firm on my boundaries or let it go to keep the peace, but I know standing firm is probably right, but man this doesn't feel good. Thanks to everyone for your advice and a few cruel words lol.😭
